- Redshift takes place when the source of electromagnetic radiation moves away from the observer. This shifts the wavelength to the red side and will decrease the frequency.
- Redshift can be calculated from frequency using the following formula,
Here fobs is the observed frequency and femit is the emitted frequency.
